Multilayered structures of multiferroic BiFeO3 (BFO) and ferroelectric BaTiO3 (BTO) have been fabricated using pulsed laser deposition (PLO). Ferromagnetic and ferroelectric properties of the multilayered system (BFO/BTO) have been investigated. It could be inferred that the magnetization increases with the incorporation of BTO buffer layer, which indicates a coupling between the ferroelectric and ferromagnetic orders. Vibrating sample magnetometer (VSM) measurements performed on the prepared multiferroic samples show that the magnetization is significantly increased (M-s=56.88 emu/cm(3)) for the multilayer system with more number of layers (four) keeping the total thickness of the multilayered system constant (350 nm) meanwhile maintaining the sufficiently enhanced ferroelectric properties (P-r=29.68 mu C/cm(2)).
